Why My New Glasses Give Me a Headache?

What color coating is good?

The purpose of plating anti-reflection film is to reduce the reflection of light. But because it is impossible to be completely free of reflected light, there will always be some residual reflection on the surface of the lens that causes the visible color. Someone asks which kind of these residual color is best. It does not have a standard actually. It is mainly based on a personal preference for color. More on the market at present is green color. However, these residual colors can initially help us to judge the thickness of the film: when the film is thin (the thickness is less than 139nm), the reflected light will show light yellow, and when the film is thick (the thickness is more than 139nm), it will show blue-green. The current multi-layer anti-reflection film thickness is about 0.3μm.


What are browline frames?

The name browline comes from the design of the frame. The upper part of the frame is thicker than the lower part so that the wearer's natural eyebrow line can be noticed. The top is usually made of acetate or plastic, and the bottom of the lens is wrapped with a thinner wireframe. Later, the browline frames have also been modified to meet the needs of more customers. Some browline frames use nylon wire instead of metal wire in the lower part, while the browline frames with metal wire are more durable and stable. If people with high myopia want to have a pair of half-rim glasses, browline frames are a good choice.



Can men wear clear frame glasses?

Clear frames are usually more suitable for younger people because they are younger and more handsome.
